Abstract
A method and apparatus for measuring the moisture content of a material wherein the measuring apparatus is positioned within a falling stream of the material to thereby continuously sample the material. The mounting angle and sideboard geometry of the apparatus are selected to give equivalent of in-bin mounting in terms of density and void to solid ratio variation so that accurate measurements may be obtained. The position of the apparatus is such that sample integrity may be visually verified and measurement error by improper sampling avoided. The method and apparatus are particularly advantageous in the manufacture of concrete wherein moisture content of sand or other granular material incorporated into the concrete must be accurately determined. The present invention allows the moisture measurement to be carried out as an in-line proceedure in the manufacturing process.
